Durco Microfinish Ball Valve - Tri-State Tech

1 Durco Microfinish ball ValveFOR CHEMICAL SERVICESThe Best Standard Stem Seal In The IndustryBulletin VM-60fDuDurco Microfinish ball valves Offer Superior Stem SealDurco Microfinish ballvalves take stem seal performance and durabilityto a new standard. Theunique stem sealing systemsignificantly enhances life cycle capability whilereducing turning the quality and performance you expectfrom Flowserve, these valves are becoming the standardof the DeviceStandard through 8 in (200 mm) NutAlong with belleville washers adjustspacking pressure to compensate fornormal wear and temperature diameter, 316SS blowout-proofstem standard on both carbon steel andstainless steel Body CavityEnhances performance in many services by minimizing media retention and process smooth finish for low torque andlong seat life.

2 CF8M/316SS is standardfor both carbon steel and stainless ElementsBall, stem and body are continuouslygrounded to eliminate static discharge. Grafoil is a registered trademark ofUnion Carbide CorporationTwo-Piece Split-BodyValve shell and seats tested per criteria. Standard materials includeWCB and CF8M. ANSI Class 150 lb and300 lb designs. Body design confinesseats to minimize seat deformation atelevated temperature. urcoFire-sealed design meets API 607,Fourth Edition criteria Metal seat at the port opening providesline seal in the event the PTFE seat burns away in a fire Stem moves up to make a metal-to-metal seal3 The Best Standard Packing System In The IndustryPositive stem seal even after100,000 cycles PTFE cup and cone packing for unsurpassed seal life and cycla-bility.

That was up to five times more cycles than the bestcompetitive Valve could fluid was 60 F (16 C) water at 290 psi (20 bar). Each Valve was fully pressurized while in the closedposition; pressure was dumped to zero as Valve cycle was counted each time the Valve was turned open and then closed.
